To all whom it may concern:

Be it known that I, THOMAS S. HOMANS, a citizen .of the United States,residing at Hempste'ad, in the county of Nassau and i State of New York,have invented newand useful Improvements in Linotype-Machines,

of Which the following is a specification.

This invention relates to improvements in linotype machines and moreespecially to the mold and means for mounting and adjusting the same,and it embodies a mold of improved construction and means whereby thesame'may be adjusted readily for various changes in the sizeof body andlength of slu .vIFh primary bjects of the invention are to enable themold to be adjusted to a line of matrices, whereby letters or charactersof 1 different font sizes located on the matrices to a common alinementbasis or any special alinement will be suitably positioned on the mold,without varying the casting position of the matrices on the machine; toenable the mold to be adjusted downwardly with respect to a line ofmatrices, whereby slugs may be cast with heavy bodies and large typefaces without aifecting the casting po sitions of the matrices on themachine and without causing a conflict between the matrix holder orelevator and the cap of the mold; and to provide improved means formounting the mold, whereby the mold will be positioned accurately withrespect to the mold. carrier and related parts of the machine and thevarious adjustments may be made readily and with facility.

To these and other ends, the invention consists in certain improvements,and combinations'and arrangements of parts, all as will be hereinaftermore fully described, the novel features being pointed out particu:larly in the claims at the end of the specification.

In the accompanying drawings :-Figure 1 is a front view of a portion ofa linotype mold disk or wheel provided with a mold and mold mountingconstructed in accordance with the preferred embodiment of theinvention; Fig. 2 represents a section on the line 22 of Fig. 1; Fig. 3represents a section taken radially through the mold disk, the mold andthe elevator which presents the matrices to the mold; Fig. 4 is a viewsimilar to Fig. 1 showing a different adjustment of the mold andillustratinga slug cast view similar to Fig. 5 showing a matri keeperemploying a single ledge; Fig. 9 is a. face View of a type slug such asthatshown in the mold in Fig. 4; Fig. 10 is a diagram illustrating themanner in which type faces of different font sizes have a commonalinement.

Similar parts are designated by the same reference characters in theseveral views.

The preferred embodiment of the invention is shown in the accompanyingdrawin s and will be described hereinafter in detall, but it is to beunderstood that the invention is not limited to the particularconstruction shown and described, as the invention may be carried outeffectually by constructions which differ specifically but are theequivalents of that shown. I In the present instance, 1 designates themold carrier or support which is in the form of a disk or wheel ascommonly employed on the well known linotype machines and having theperipheral gear teeth 2 whereby the mold is brought to the casting,trimming and ejecting positions. According to the present invention.each mold is mounted on pads or lugs which project from the face of themold disk or carrier, a pair of pads or lugs 3 and 4 being shown in thepresent in stance and these pads or lugs serve to gage or accuratelyposition the mold with respect to the mold disk or carrier and to securethe mold adjustably thereto. These pads or lugs have suitably finishedopposed surfaces 5 and 6 which are adapted to cooperate with the ends ofthe mold body, thereby positioning the same in a longitudinal direction,and these pads or lugs also have suitably finished surfaces 7 and 8which serve to accurately gage or position the mold with respect to thecenter of the mold disk or carrier.

The customary practice in the operation of the usual linotype machinesis to adjust the mold cap only when changing the 'mold to cast lines oftype or slugs of different body sizes. Such practice resulted in locat-1 ing the matrix face of each different font size in a differentposition of alinement. For example, in Fig. 10 the lines ab and ccZrepresent a large slug having the characters H and j thereon, and thelines e-f and gh represent a smaller slug bearing the same charactersbut of smaller font sizes. The line a-b represents the line of the bodyof the mold and the line 0-0? representsthe line of the cap of the moldrelatively to the larger slug, and the line e f represents the line ofthe body of the mold and the line g-h the line of the cap of the moldwith respect to the smaller slug. It is obvious that if the mold capwere lowered or brought nearer to the body of the mold in order to casttype of the smaller size face while the body of the mold remainedstationary or fixed, the alinement line represented as Z-Z in thediagram would have to be lowered also in order to properly locate thetype of small size, and hence the necessity heretofore of positioningthe matrix faces bearing letters or characters'of different sizes, atdifferent levels. Therefore, if the alinement line 1-1 is to remainconstant for type faces of different font sizes, the mold body must beadjusted according to the adjustment of the mold cap, or the matricesmust have varying casting positions on the machine. The presentinvention provides a mold the bodv and cap of which may be adjustedreadily and type faces of different font sizes may all be cast on theslug in common alinement. In the present embodiment of the invention,the mold body 9 abuts against the positioning faces 5 and 6 of the padsor lugs 3 and 4 but is capable of adjustment in parallelism with thesefaces, the reduced portion 10 of the mold body bearing against a face ofthe mold disk and longitudinal extensions 11 and 12 project from theopposite ends of the mold body and beneath the pads or lugs 3 and 1-.Screws 13 and 14. extend through the pads or lugs 3 and 4 and thethreaded portions thereof cooperate with the extensions 11 and 12 of themold body, and turning of these screws in appropriate directions servesto adjust the mold body to vary the dimensions of the mold cavity tocast lines of type of different body sizes. The matrix keeper 15 whichserves to properly position the line of matrices for the mold, accordingto the present invention,'occupies a fixed relation to the mold disk orsupport, this keeper in the present instance bearing against the outerface of the reduced portion 10 of the mold body and is secured in fixedrelation to the mold disk by the screws 16. The matrices may bepresented to the mold by the usual first elevator which is designated 17in the present instance, the matrix keeper 15 having one or more ledgesto cooperate with the ears on the matrices. In Figs. 1, 3, 4, 5 and 7,this matrix keeper is provided with two ledges 18 and 19 whereby twoletter matrices may be positioned at two levels before the mold, whilein Fig. 8, the matrix keeper 20 has a single ledge 21 to coiiperate withthe ears of single letter matrices. By using an adjustable body mold anda relatively fixed matrix keeper, the matrices will occupy an invariableor constant position with respect to the casting mechanism of themachine.

The mold cap 22 may be of different constructions, that shown havingextensions 23 and 24- which are adapted to project over the pads or lugs3 and 4:, and the mold cap may be adjusted to conform with theadjustments of the mold in casting lines of type of different body sizesby liners which are interposed between the mold cap and the positioningsurfaces 7 and 8 of the pads. The

present invention provides liners of improved construction which performthe dual function of spacing the distance between the mold cap and body,and positioning the mold cap with respect to the pads or lugs 3 and 4 onthe mold disk. Each liner in the present embodiment of the inventioncomprises a section 25 which is adapted to rest upon the top gagingsurface 7 and a section 26 which is adapted to project more or less intothe mold cavity according to the length of the line of type to be cast.The thicknesses of these two sections 25 and 26 of each liner will varyaccording to the ad justments of the mold cap with respect to the molddisk and the distance between the mold cap and body, the upper surfacesof both sections being in alinement and in the same plane to fit closelyagainst the outer surface of the mold cap, while the lower surfaces ofthe liner sections may he stepped or in different planes according tothe different adjustments. Each liner may be pro vided with a transverserib 27 to engage-in or lug to position the liner properly in a directionlongitudinally of the mold, and

each liner may be slotted as at 29 to accommodate the screws 13 and 14:previously described and the screws 30 and 31, the liner being adaptedfor insertion and removal by a transverse movement, that is to say, amovement longitudinally of the transverse rib 2-7. The mold cap and theliners interposed between it and the pads or lugs 3 and 4c are securedto the mold disk by the clamp ing screws 30 and 31 which pass throughthe extensions 23 and 24 of the mold cap and are tapped into the pads orlugs 3 and 4, while as previously stated, the screws 13 and 14: serve tohold the mold body in differcnt positions of adjustment relatively tothe mold disk. The sections 26 of the liners,

when the screws 13 and 14 are tightened, those sections of the linerswill serve as gages to set the mold to cast lines of type of theselected body size.

Another feature of advantage obtained by the present invention is that arelatively wide range of adjustment is provided for the mold withoutinterfering with the elevator which presents the matricesto the mold.Such elevators as used upon the well known linotype machine have anoverhanging portion 32, and in following the usual practice of adjustingthe mold cap only, the mold cap encountered the overhanging portion 32of the elevator and thereby limited the adjustment of the mold toenlarge the cavity thereof. However, by adjusting the mold body as wellas the mold cap, itis obvious that a considerably greater range ofadjustment is afforded and slugs of a maximum body size may be castwithout changing the operative position of the elevator which presentsthe matrices to the mold and without altering the relation of thematrices to the relatively fixed matrix keeper.
